Description
Heed Legrange S
The Heed Legrange S is a high-end audiophile amplifier at a very realistic price considering the build quality and performance.
Being a Transcap amplifier, the Lagrange has all the benefits of the technology that can create this rich and organic sound. The level of details, the pace, the rhythm and the overall atmosphere of the music are all in lovely balance. Choose any aspect you like, you will find what you seek for, and you will enjoy it very much.
Heed’s first full size integrated amplifier offers an optimal Heed experience.
Heed believe there is a sweet spot for almost everything. In music, the balance of sound and silence, the ratio of the tempo to our heartbeat, or the weight of each instrument induce many different experiences. They give us pleasure or sorrow, evoke fragments of memories in rapid succession, which all evolve to an overall emotional picture about that piece of music.
When we speak about balance in music reproduction, we cannot describe it with numbers. For this reason, Heed products are not made to bend lines on an oscilloscope, but to give you one of the greatest delights in life, the joy of music. And Lagrange is exceptionally good at that.

Hand Crafted
Creating something is a wonderful feeling. To witness the numerous pieces of electronic and mechanical parts being hand crafted to form a complete working device is delightful. Every single component receives exacting attention and is the perfect element to provide you with an unrivalled musical experience.
From the hand soldering of the circuit boards to the fine adjustments of the volume knob, we ensure every process and incorporate only the highest quality components to make a Heed amplifier the best in class. Rigorous quality control provides the highest possible standard and reliability of our devices. Every single device meets our strict performance regulations but similar to twins, we know that each and every one produced is unique to you.
Transcap
When you own a Heed amplifier you meet technology that you most probably have never seen in action before. Like the almost forgotten (and then reincarnated) valve technology, the output capacitor transistor amplifiers can normally only be found in the deepest recesses of engineers drawers. The technical difficulties of RC-Coupling means almost 100% of todays manufacturers opt for the easier direct-coupled solutions instead. With great effort and countless development hours there is a way to employ an up to date and sonically better sounding RC-Coupled amplifier. We have chosen this way.
Like the belt of a great turntable or the output transformer of a valve amplifier, the output capacitor makes for a great decoupling between the amp and the speaker. But the main advantage is the fact that a capacitor is an energy storage device. By design, this capacitor connects directly onto the speaker, with no in-between elements. Power delivery becomes rapid and precise. To charge this power element, we use a push-pull complementary Darlington transistor drive stage.
This power transforming system needs to be perfectly balanced. The heart of our Transcap technology lies in the precise adjustment of all the charge transmitting and current delivery channels. This propels all the common amplifier components; mains transformer, power supply, voltage and power amplifier stages, into something radically different. You may see now, this is no ordinary amp and it cannot be measured by common standards. Using our methods the sound becomes thick, warm, yet clear and life-like, as it properly translates the electronic signal into the acoustic world.
TRANSMISSION-LINE-REFLEX SPEAKER LOADING
Every dynamic speaker driver needs some kind of acoustical load to work as it should. The most common solution is a cavity attached onto the back side of the diaphragm. This speaker box may be closed or vented. The vented ones are trickier to design because there are many parameters impacting on the result. There are ‘rule of thumb’ designing guides to make such boxes as bass-reflex, transmission-line, open baffle, compound or horn loading, each of them handled like an entirely different solution.
Acoustics are however based on physical facts. If we use a vented enclosure with an opening at one side, it will be a resonant chamber, even if we use it as a transmission-line element. The adjustment of such enclosure needs extra care and attention. Incorporating all known calculating methods we build enclosures that fit all aspects. This is the perfect way to slip between working states, achieving the crisp, fast and rhythmical but yet fluid and almost organic sound we oh so like
